fix(@angular-devkit/build-angular): warn if using partial mode with application builder

The Angular compiler's partial compilation mode is only intended for use when building libraries.
If attempting to use the mode while building an application, the application would fail. A warning
is now issued if partial mode is configured for the application and the mode is switched to full
compilation mode to prevent the build from failing due to the option value.
